To 22 whom it may concern:

T c it known that We, THOMAS ALLsor and Wanrna W. SIBSON, citizens of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Drying or Otherwise Treating Mannfactures whereof the following is a specification, rei'- erence being had to the accompanying drawings, v

@111 invention relates to apparatus for drying and other treatments and is concerned with various phases of such opera 15 lilOi'iS; including the mode and conditions of application of the treating medium to the articles or products to be treated and the presentation of the articles to the medium e aim to provide for controlling and iliil iting the sphere of action of the treating in-ecinin, without interfering with the intro duction and Withdrawal of the material to he treated; to provide for circulation of the treating medium; and to provide for carrying on a plurality of treatments concurrently but separately, and more or less independently or" one another. Also the air which constitutes the treating medium may he physically modified in various Ways, to produce correspondingly difierent results. material to be treated may he slowly carried through the treating zone or zones by a conveyor.

in the drawings, Fig. I shows a longitw dinal'section (more or less diagrammatic) through an apparatus conveniently embody= ing our invention in one form.

Fig. "H shows a cross section through the apparatus, taken as indicated by the line ill-ll in Fig L Fig. IE is a view similar Fig, I, showing an apparatus with a plurality of sepa rate treating compartments.

The apparatus shown in Fi s. l and ii comprises a quadrangular enc osure 1 and a partitioning structure or unit 2 of general i-l-shape therein, with sides and transverse APPARATUS FOR DRYIEQG 0R G THEEW'IEEE TREATING M33553 Application filed November 18, 3919, Serial 31o. asaocv.

Apparatus of the character described carrying on ofa varieti ments, by extension of e" scheme ot-subdi- Vision. While only two'treatingcompartt ments are shown, it will be seen that on the principle illustrated, they can be duplicated indefinitely in a more extensive apparatus 7 for effecting a greater number or variety of separate consecutive treatments As shown in Fig. III, partitioning structures 25, 25 corresponding to thatgmarked 2 in Figs. I and II afford a like number of separate treating chambers or compartments 26, 27. Besides being spaced from the corresponding enclosure walls to afford spaces or channels 28, 29 corresponding to those marked 4, 5 in Fig. I, the structures 25 25 are separated to afford a space or channel 30 p -'t1on of air substantlally' confined to the inbetween them, which is connected to each of the spaces 28, 29 by a space or channel 31 corresponding to the space or passage6 in Figs. I and II. Besides pass ng throughv the compartments 26, 27 and being diverted into the end spaces 28, 29, and even traversing the channel 31, as before, the conveyor also passes through a space outside of either compartment 26, 27 on its way from one to the other, so as to avoid direct transfer of 33 correin Fig. I,

and forming separate inner spaces or chambers 34 and 35, 35, with a space 36 between the transverse members of the U 33 and that of the U 25, and a rotary fan 3'? arranged for circulating the air as in Fig. I.

Thus, it will be seen that although the treating compartments 26, 27 open into a common space in the top of the enclosure,
